    Oil for Sturmey-Archer hubs?

    Hi, what oil is best for Sturmey-Archer hubs, and what can go wrong with the wrong stuff? What about Tri-Flo?

    I've read somewhere on the forum that the factory lube is like a 20W oil. Although somebody said that they used automatic transmission fluid with good results. It's a higher heat resistance, an oil specifically made for high stress gears. You should do a forum search.

    Do not use 3 in 1 as it can gum up due to the vegetable oil component. Generally speaking 20 or 30 weight oil was the factory recommendation. Genuine Sturmey Archer oil was a 20 weight non detergent oil per what I have read.

    Current production S-A hubs warn not to use oil - take them to a S-A certified shop for repacking with grease.

    I put in whatever I'm using for the car, either 5w30 or 10w30.

    I suspect anything will be adequate, though straight 20w or 30w without detergent would be ideal.

    Other bad substances:
    WD-40
    kerosene
    grease
    3-in-1

    I'm using ATF nowadays but haven't run the hub for long enough to report the results. Pink is my favorite color, so I had to try it.

    ATF works fine. As does Phil Wood Tenacious Oil.

    Sturmey tips from Mark Stonich.

    Lubrication:

    Modern factory Sturmey greases: gear, SA103A
    bearing, SA103B

    Sturmey SA103A is a semi-fluid, NLGI #00 grease, a product that has been developed for industry to replace oils in gearboxes either for longer service life or because the gearbox has developed a leak. That should do fine, if only you can find a small quantity.

    How about oil? I've seen the following recomended, all of which seem reasonable:
    20wt motor oil
    30wt motor oil
    10W-30wt synthetic motor oil
    automatic transmission fluid
    75W-90 gear oil
    75W-90 synthetic gear oil
    sewing machine oil

    Of these I'm personally attracted to the 75W-90 synthetic gear oil. It's locally available in quarts, it's not terribly expensive, it has extremely long shelf and service lives, it's designed for use in non-pressurized lubrication systems and as a purpose designed gear lubricant it has anti-sheer additives.

    HTH,
